TILE-MACHINE.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed February 5,1907. Serial No 355,835.

and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Tile Machines, of Which the following is a specification.

My invention relates to improvements in tile-machines, and the object of my improvement is to provide proper mechanism for forming tile of any diameter quickly and perfectly from cement material. This object I have accomplished by the mechanism which is hereinafter described and claimed, and wvhich is illustrated in the drawings annexed hereto, in which Figure 1 is a side elevation of my improved tile-machine, Fig. 2 is a front elevation thereof, and Fig. 3 is a detail view of the mounting of the eccentric-block, portions of the tileforming mechanism in Figs. v1 and 2 being shown in central vertical section to better disclose the interior construction.

Similar reference numerals refer to similar parts throughout the several views.

My machine consists essentially of an outer and inner casing or molds for forming the tile, such casings movable about each other.

The former-casing 1 has an exterior ring 4 around it, said ring having a bracket-box 13 for the pinion 52 to rotate in, said ring 4 resting on the bracket-arms 9 which extend forwardly from the cylinder 23, the latter slidable vertically on the pillar 24. The casing 1 is rotatable within the ring 4, and another ring 5 is attached to said casing and rests upon the ring 4, antifriction balls being interposed between them. The exterior circumferential periphery of the ring 5 is provided with gear-teeth adapted to intermesh with the teeth on the pinion 52, the latter being slidable on a feather 48 on the shaft 10 which is rotatable in the step-bearing 11 and the bearing 43. The frictioncones 36 and 37 are keyed to the upper end of the shaft 12, over its bearing box 53, and connected by a sleeve, and between said cones to the rear thereof a driving-cone is arranged at a right angle thereto and adapted to drive either one alternately when vertically shifted into the proper driving-contact therewith. The shaft 30 on whose forward end the driving-cone 35 is fixed, has keyed thereto an eccentric-sheave 33 rotatably mounted in an eccentric-strap 54 on the standard 51, the latter integral with the horizontal member 25 of the frame by whichit is supported. The eccentric-sheave 33 is fixedly connected to the cone 35-by rods 34. The driving-00110 35 is moved upward into driving contact with the upper cone 36 by moving the lever 32 downward, and downward into driving contact with the lower cone 37 by shifting said lever upward. The rear end of the shaft 30 is rotatably mounted in a bearing-box in the upper part of the frame 25, the end of said shaft having a retaining collar 29 secured thereto. The upper frame 25 is supported on the pillars 24 and 27 and secured thereto by means of bolts 26 and 28 respectively. The shaft 30 is rotated by means of a gearwheel 31 secured thereon, the latter being driven by a pinion 40 secured to the parallel horizontal shaft 39 whose front end is rotatably mounted in a bearing 42 and whose rear end is rotatably mounted in a bearing 56, a retaining-ring 38 being secured to the rear end of said shaft 39. The shaft 39 is rotated by means of a belt-wheel 41 secured thereon. The shaft 12, having an exterior screw-thread is rotatably mounted in an in teriorly threaded vertical opening in the bracket-body 9. Secured to the upper end of the shaft 10 is a bevelgearwheel 45, set between the retaining-rings 44 and 47 also secured to said shaft. The gear-wheel 45 is driven by means of an intermeshing-bevelpinion 46 secured to the forward end of the shaft 39. The inner periphery of the formercasing is provided with a spiral inwardly inclined thread 2 for a purpose to be described hereinafter.

Underneath the lower edge of the formercasing 1 and adapted to contact therewith when said casing is in its lowermost position, is a flat table 3, movable horizontally and transversely over rollers 6 rotatably supported in uprights 7 attached to the bed 8 of the machine. fag

A bracket arm 21 is fixed to the machineframe, and has laterally extending lugs 56 to which hangers 14 are secured by means of bolts 22. The hangers 14 support a housing ring 57 whose inner edge is flush with the inner edges of said hangers, but whose outer edge extends outward beyond the outer edges of said hangers to a distance equal to the thickness of the tile to be made. A rack-bar 16 is vertically movable through a vertical opening in the bracket 21 and meshes with the teeth of a pinion 17 mounted on a'shaft rotatably set in bearings in uprights 19 on said bracket 21. The shaft 18 is rotated by means of a hand-crank 20. To the lower end of the rack 16, below said bracket 21 is secured a downwardly depending hollow trun cated cone 15 to whose lower edges is con nected a hollow and bottomless cylinder 58. The said cylinder has its outer periphery in bearing contact with the inner edges of the hangers 14, which thus serve as guides to keep the cylinder from vibration in its reciprocatory movement. The upper part of the former-casing 1 is bulged outwardly to a greater diameter than its lower portion, to afford a hopper for the easy deposit therein of the soft tile material. The space between the lower portion of said former-casing 1 and the inner cylinder 58 is equal to the thickness of the tile to be formed therein.

Fig. 2 shows the machine in the position for receiving the material to form a tile. The former-casing 1 is in continuous rotation driven by the means described. The tile material is deposited within the former-casing 1 at its top between it and the cylinder 58, and the cylinder then elevated by the means described. Before the said cylinder is elevated, however, the former-casing is caused to move upward by turning the lelever 32 in the proper direction, the eccentricsheave thus causing the driving-cone 35 to rotate the proper cone on the shaft 12 to cause the screw on the latter to elevate the bracketarms 9 with the ring 4 and said former-casing 1. As the former-casing 1 rotates and simultaneously moves upward in a vertical direction, its resultant movement is spiral, and the thread 2 therein acts spirally upon the plastic mass of tile material inside, rubbing and pressing it closely and homogeneously against the outer periphery of the cylinder 58 and forming the tile to the removement, said casing having an interior quired thickness thereon. When the formercasing is elevated to such a height that its lower edge is slightly above the lower edge of the ring 57, the inner cylinder is withdrawn upwardly from the newly formed tile by the means described. The tile, which rests upon the table 3, is with such table, then with- I drawn from the machine over the rollers 6. The former-casing 1 is then returned to its lowermost position by moving the lever 32 back, and the cylinder 58 returned by the hand-crank 20. l

2. In a tile-machine, in combination, an

outer former-casing adapted for simultaneous rotatory and progressive longitudinal movement, and a removable mold casing contained therein.

3. In a tile-machine, in combination, an outer former-casing adapted for simultaneous rotatory and progressive longitudinal thread, and a mold casing contained in said outer casing.

4. In a tile-machine, in combination, an outer former-casing adapted forsimultaneous rotatory and progressive longitudinal movement, a removable mold casing therein, and means for raising or lowering said outer casing independently of the movement of the inner casing.

5. In a tilemachine, in combination, an outer rotatable casing, means for moving said casing in either direction, a removable inner casing spaced apart from said outer casing, and a removable base-plate for said casings.

6. In a'tile-machine, in combination, an outer rotatable casing, means for imparting longitudinal movement to said casing in either direction along the line of its aXis, a removable inner casing therein and spaced apart therefrom, a removable base-plate for said casings, and means for moving said inner casing in and out of said outer casing independently of the movement of the latter.
